PURPOSE:To enhance bedsore preventing effect by easily dispersing the body pressure of a patient and promoting air drying by embedding a plurality of pipes each having air blowoff ports bored therein upwardly in a built-in fluffy fiber material having air permeability and cushioning properties and providing an air pump for introducing air into the pipes. CONSTITUTION:A fluffy fiber material 2 having air permeability and cushioing properties is received in a mattress 1 and a plurality of air blowoff ports 4 are bored in the pipes 3 embedded in the fluffy fiber material 2 upwardly and an air pump for sending air into the pipes 3 under pressure is provided. The fluffy fiber material 2 is constituted by entangling fibers composed of a polyester, nylon, polypropylene or an acrylic resin and each of the pipes 3 is constituted of a flexible synthetic resin such as a soft vinyl chloride resin. By this constitution, the body pressure of a patient can be easily dispersed and the air blown out of the ports of the pipes passes through the fluffy fiber material to be dispersed to enable natural ventilation and air is forcedly sent to a part high in body pressure to promote air drying. |
